METAL ROPE.

SPECIFICATION forming part of Letters Patent N0. 338,913, dated March 30, 1886.

.Application led M ay 16, 1885. Serial No. 165,693. (No model.) Patented in England March 31, 1884, No. 5,724; in France October 1, 1884, No. 151,988 in Germany October 2, 1884, No. 42,088, and in Belgium October 2, 1884, No. 48,726.

To all whom it may concern:

Be it known that I, TELEORD CLARENCE BATCHELOR, a subject of the Queen of Great Britain, residing at N o. 2 New Castleton Road,

West Kensington, in the county of Middlesex, England, engineer, have invented certain new and useful Improvements in Metal Ropes, (for which I have received Letters Patent of Great Britain, No. 5,724, dated March 3l, 1884; of France, No. 151,988, dated October 1, 1884; of Germany, No. 42,088, dated October 2, 1884, and of Belgium, No. 48,726, dated October 2, 1884,) of which the following is a specication.

Before particularly' describing my invention '1 will remark that it is not limited in its application to what are commonly called ropes, which are of round form, but is applicable to strands which form the component members of ropes, and also to ropes or bands of flat form, and'therefore by the term rope, as hereinafter employed, I wish to be understood as including also a strand which is a member of a larger rope, and also a flat band.

The object of my invention is to obtain a metal rope in which the ends of any of its external wires, strips, 0r primary members that may become fractured may be retained in place. To this end I so construct the external wires or strips of the rope of tongued, grooved, rabbeted, dovetailed, or other equiv alent form, presenting on the adjacent members longitudinal matching projections and recesses of such nature or form, and so combine the said members that a portion of each of said members underlies a port-ion of an adjacent one; and my invention consists in a rope having its external members so constructed and combined. 1

The invention is applicable to ropes the component wires or members of which are twisted or spirally arranged, and to ropes or bands in which the members are laid together without twisting.

Figures 1, 2, 3, 4, 5, and 6 represent transverse sections of six different examples of metalrope or cable constructed according to my invention, and having the external wires,

strips, or members twisted or spirally laid together. Fig. l* is an external longitudinal view corresponding with Figs. 1 and 4. Fig. 2* is an external longitudinal view corresponding with Figs. 2 and 5. Fig. 3* is a longitudinal view corresponding with Fig. 3. Figs. 7 and 8 represent transverse sections of two forms of dat band the members of which are united according to my invention, but. without twisting. Fig. 8 is a face view corresponding with Fig. 8. Fig. 7" is a transverse sectional diagram corresponding with Fig, 7, and illustrating the method of manufacture.

Similar letters of reference indicate corresponding parts in the several figures.

In the-examples shown in Figs. 1, 2, 3, 4, 5, and 6 the metal rope or cable is represented 6 as having a central core, b, which may be of hemp or other fibrous material, or of metal wire, and may be simply twisted or laid t0- gether as in ordinary rope; but the exterior spirally-arranged wires, strips, or members, a a az aa a* a5, are all of such transverse sectional form that they present tongues and grooves, rabbets, or other matching longitudinal projections and recesses throughout their length, whereby either member breaking would have 7 its fractured ends confined by portions of them underlying a portion of the member on one side or portions of those on both sides of them.

In Fig. 1 there are represented two concentric circular series of external membersnviz., an outer series, a a, and an inner series, a a. These are all of similar transverse sectional form, being round on one side and hollow on the opposite side, and the round side of one is arrangedl next to and within the hollow side of the other, so that they are practically tongued and grooved together, and so that while they are placed in a spiral relation those of each circular series hold each other through,- out their length in such manner that if one should be broken its fractured ends could not -break away outwardly from the rope, because they would be confined by portions of them i underlying portions of the members on both sides of them.

In the example shown in Fig. 2 the external members, a, are in a single series, round on one side and hollow on the opposite side, and

littogether and hold one another in place, as.

strips or members, a a, which are tongued and grooved along their sides in such manner that while they are spirally laid together a portion of each underlies a portion of one of the adjacent ones,so that `they cannot get away from each other, even though fractu red transversely.

In the example vshown in Fig. 4' there are two series of spirally-laid external strips or members, a a, one within the other, as in that shown in Fig.r1.

. corresponding longitudinal rabbets, forming matching projections and recesses, by which the strips when they are spirally laidare gonined throughout their whole length by a portion of each underlying av portion of that on one side of it.

In the example'shown in Fig. 5 there` are also two circular series of metal strips, which are of such form that when laid together side by side in a circular series they present to each other matching tongues and grooves, by which, when they are spirally laid together, each is retained in place by underlying portions of those onboth sides of it.

`In the example shown in Fig. 6 there are several circular series of members, each series consisting of alternating simple round wires a, a', or a, and intervening strips, as, a, or a, which are grooved longitudinally to receive the said wires, in such manner that the adjacent members, consisting of the alternating wires and grooved strips in the circular'series, present to each other matching longitudinal projections and recesses, and when spirally laid interlock and confine each other throughout their length by a portion of each under lying a portion of that on each side of it.

These strips are made with In the manufacture of the ropes heren.

or members may bev twisted or laid together Vby machines like those'commonlyused in the manufacture of wire rope.

'The at rope or band-illustrated by Figs. l7 and 7-h is composed of a single series of strips, a a,'of metal, arranged side by side in reverse order. In the finished band the members or strips a a are unitedl throughout `their whole length by dovetail tongues and grooves, as shown in Fig. 7. These strips or members before being assembled are not dovetailed, as,

'if they were, they could not be put together;

but theyare made with simple tongues and grooves, as shown in Fig. 7", and after having been laid together as shown 4in that figure they are passed between plain rolls or through a die, by which their tongues are spread'into dovetail form, and the members are all made to present plane surfaces at their,` exteriors, and combine to, form the dat band shown in Fig. 7.

The example illustrated in Figs. Sand 8* consists of two bands-such as are shown in Fig. 7-united at their edges at intervals by dovetail clips c c.

In bot-h of said examples of flat ropes or bands a portion of each external strip underlies a portion of that on each side of it.

WhatuI claim as my invention, and desire to secure by Letters Patent, is-

A metal rope having its external component wires, strips, or members constructed with longitudinal matching project-ions and recesses, substantially as herein described, and combined as herein set forth, whereby a portion of each underlies a portion of an adjacent one.
